PORT ADELAIDE has been forced into another change to its line-up for Sunday’s twilight encounter with Greater Western Sydney with Travis Boak to miss the match through illness.

Boak did not complete the captain’s run with the side on Saturday morning and has been withdrawn from the 22 named on Friday afternoon.

Forward Francis Evans takes Boak’s place on the interchange bench, and Riley Bonner has been added to the list of emergencies alongside Jase Burgoyne, Sam Hayes and Quinton Narkle.

The tactical substitute will be selected from among the emergencies an hour from the 4:10pm first bounce on Sunday.

Ruck Dante Visentini was previously withdrawn on Friday after experiencing quad tightness at training with Hayes taking his place in the squad and included as an emergency.

Port Adelaide’s players will wear a special retro guernsey during the game, paying tribute to tri-bolt design first worn in the pre-season in 1998 and adopted as a clash guernsey for the 2003 season.

Sunday’s game at Adelaide Oval gets underway at 4:10pm. Tickets are still available for the match.
